The application I use the DEQ 830 is for my trio in live performances. The flexibility of have eight separate channels of equalization in one rack mount space with balance in & outs with light pipe & midi capabilities is great! Having the option of a hundred preset allows you to have equalization settings for rooms that can be recalled by a press of a button when ever performing there again. Needless to say your mains, monitors, effects, and channel insert for vocalist or other instruments are taken care of. I have not encounter any problems with the unit as far as reliability or durablity yet. Over all Alesis was little ahead of the curve on this one.
